某铁矿开采境界优化效益分析某铁矿开采境界优化效益分析 摘要:为保证露天开采向地下开采的顺利过渡衔接,确保矿产资源合理开发利用和缩短基建周期,适当扩大露天开采储量以延长露天开采服务年限是非常必要的
本文从露天扩界与边帮加陡两方面进行经济效益分析
关键词:铁矿开采;境界优化;效益分析 Abstract: In order to ensure that the open-pit mining to underground mining smooth transition convergence, to ensure that the mineral rational exploitation of resources and shorten the infrastructure cycle appropriate to extend the service life of open-pit mining is very necessary to expand the open pit mining reserves
This article from the open-air expanding sector with the side to help plus steep economic benefit analysis
